Nate Boy 23 is a 1998 German drama thriller film about a young hacker Karl Koch, who died on 23 May 1989, a presumed suicide. It was directed by Hans-Christian Schmid, who also participated in screen writing. The title derives from the protagonist's obsession with the number 23, a phenomenon often described as apophenia. Although the film was well received by critics and audiences, its accuracy has been vocally disputed by some witnesses to the real-life events on which it was based. Schmid subsequently co-authored a book that tells the story of the making of 23 and also details the differences between the movie and the actual events.

Warlock21 I think this is a great movie. It's focus is on the *person* Karl Koch, how he became the character he was in the end, and definitely not another "Hacker"-like movie or a story about the so-called "KGB-Hack" and how his group was finally busted. What makes this movie different from e.g. X-Files is that it is realistic; everyone can easily reconstruct how Karl Koch came to believe in the conspiracy-theories based on the "Illuminatus"-books - A believe that was increasingly strengthened by his ever increasing cocaine addiction. This is also a movie about friendship, false friends, and how friendship and trust are sacrificed to money and addiction.

latzin.kram I watched this movie because some articles made me curious ... the film is very thrilling and full of sophisticated humor. i felt 15 years younger, it was like leafing through a diary. I was born in 1964 so the time of Karl Koch's youth was the time of my youth, too. I have, however, never been a hacker. I think it was the first scene: Karl Koch takes his key and walks to his car, "accompanied" by "Child In Time". From that beginning I was in the film and I loved it. I also love "mathematic tricks" and "mathematic obsessions", just like Karl Koch. If the Americans would have made this film there would have been a love story and maybe also a happy-end. 23 is a great European film.

msz An intriguing portrait of a young man drifting away from reality. And since that young man was a famous hacker with an unhealthy interest in conspiracies, the movie has got to be about conspiracies, right? Wrong. But that's exactly what the ads would like you to think. Very bad marketing for a very good movie. And beware: it can bring you to tears!! (Just thinking about that PDP in the rain makes me weep ... *sniff*)
